Applioationlanuary Z5. 1936. Serial No. 60,778 7 Glaiml- (Cl. 301-86) The present invention relates to demountable wheels and more particularly to a mounting for demountable dual, disc wheels.

The main object oi the invention is to provide 5 a dual disc wheelhaving interchangeable inner V and outer discs -identical in shape and dimension and capable ot being interlocked without sacrince of identity of shape and dimension of the in'- terlocking members on the different discs or the l. interchangeability o! all accessory mounting elements.

Another object is to obtain maximum strength with' a given weight of material and at the same time attain a strong driving connection between 1| the wheel discs and between the wheel discs and hub while relieving the clamping-on bolts of shearing stresses, thereby permitting the use of minimum size clamping-on bolts. v A further object is to provide for improved cenzo tering, binding and wedging action in the clamp. ing o! the discs to the hub with inter-engaging parts of suiclent resiliency to eliminate lost motion and act to keep the bolting-on nuts tight.

Other objects and advantagesot the invention u will be apparent from a perusal of the following specincation and the drawings accompanying the same.

In the drawings: e'

ll'ig. 31s a sectional view on lined-4 of Fig.. 1 sho a second set of attaching means.

4 is an axial -view along the line 4-4 oi o ,subetantlally uniform cross section, anda portion l I2 beyond the boltlng-on flange portion o! gradual and mtanueuy unironn taper extending through the remaining portion ofthe disc. The ilanged periphery of the disc is secured to the u wheel rim I3 in any known or other suitable manner, as by arc welding,as is indicated at I4. V The discs are of the demountable wheel type and are provided with axially offset inter-nesting and bolt seating bosses Il about the bolting on gn holes I4. These bosses are identical in shape and dimension, but are oilset axially,-alte rnately in opposite 'as'shown in Pig. 4. lach boes has a central bolt hole therethrough and is` i'ormed with a conical radially outer surface por- .with

radially inner, axially oppositely facing conical boltl seats I0 and' I9, respectively, at the reversev and protruding sides of the boss.. As shown in Fig. l the bolt holes are equally' spaced around the bolting-on flange I I. Conical seats 2li formed 5 in the hub flange 2 l are of the same angularity as the radially outer conical surfaces I1, andare equal in number to the bolt holes and similarly spaced so as to register therewith. As the bosses alternate in their direction of oiset conical ra- 10 dially outer surfaces of thre'e alternate bosses will engage with the hub seats 2li.A

Clamping bolts 22 are secured in the hub flange at each of the hub 'seats 20 and extend axially outwardly therethrough so as to pass through the 15 openings in the bolt hole bosses in the discs as shown in Fig. 4, and are threaded at their outer ends to receive the clamping nuts 28 provided with conical inner faces 24. As the angularity of the conical face 24' of the clamping nuts 23, 20

the radially outer conical surfaces I'l and the radially inner oppositely facing conical surfaces. I8 and I9v of the bosses are of the same angularity, the nuts 24 are adapted to engage interchangeably with either of the oppositely vfacing radially in- 25 ner bolt seats I8 and I9, respectively,l while the conical bolt seats I8` are adaptedto receive either a clampingnut 23 or the radially outer conical surface of the boss of another disc.

Because ofthe peculiar shape and arrangement 3o of the bosses, whereby they are provided with the radially inner oppositely facing, conical bolt seats and oiset to provide a radially outer conical suri'ace,'all of equal angularity, it is possible to make all o1 the bolt holes of the same diameter 35 and the bosses ofidentical shape and 'at the same time have all the bosses o n the different discs interchangeably inter-nesting as shown in Figs. 2,3and4. v'

With theI two wheels clamped in place on the hub, as shown in Fig. 4, axially inwardly extend- 'ing bosses will engage as shown at the upper part of IIig.` 4 lwhere it will be seen that the radially outer conical surfacey I'I oi a boss on the `axially inner disc is nested'within a conical hub 45 seat 2l while the radially Aouter conical surface I1 of a boss onthe'axially outer discnests'in the radially inner conical seat ,Il oi the boss on the axially inner disc, the clamping nut 2l hold. ing the parts clamped in this position by en'- 50` gagement ,of its conical surface portion 24 with Y the radially'inner conical seat I8 of the axially outer disc. The,clamping bolt and nut thus hold the two'discs and the hub together against relative rotational movement, the torque being u transmitted from the hub directly to the axially inner disc through the ani inwardly oiiset boss and :from the inner disc to the outer disc through the internesting onset bosses of the dii'- ferent discs without shearing strain on the clamping bolt, whereby the clampingv bolt may be made of minimum size to exert V the required axial thrust or clamping action between the clamping nut 23 and the hub ange 2l.

The other alternate bosses projecting axially outwardly of the hub, (toward the right in lllg. 4) engage as shown. at the lower part of Fig. 4. Here neither oi' the bosses engage the hub seat 20 but extend axially outwardly so that the radially outer conical surface Il of the axially inner disc engages the radially inner conical surface I8 at the reverse side of the boss on the outer or right hand disc and in nested relation thereto, the

discs being clamped together and against the hub ange by engagement of the conical surface 24 of the clamping nut 23 with the radially inner conical seat i9 of the axially outer disc.

Here also the bolt is relieved of shearing stresses as the outside or right hand disc receives its drive from the inside disc locked to the hub l through the axially inwardly projecting bosses on the inside disc. As all the parts are identical in shape and dimension, the same nuts 23 may be used for engagement with the alternate oppositely onset bosses, and either disc may be used as the axially inner or outer disc oi' the dual wheel.

It will be noted that the peculiar angular oil!- set of the walls of the bosses have two important consequences. In the nrst place, this angular Oset provides a rigid section which strengthens this portion oi' the whe'el and helps to carry the radial load. Secondly, the radially outer conical surfaces of certain of the bosses eii'ect a centering and wedging action to center the wheel and take up all lost motion,l providing a very-secure and positive connection between the innendise and the hub flange. Thus the driving torque is taken directly through one set of alternate bosses which interlock with the hub ange, the other set serving to interlock the wheels together, with substantiallyino shearing stress on the bolts.
